The title compound, [Zn(NDC)(2,2′-bipy)]n (NDC = 1,5-naphthalenedicarboxylate, 2,2′- bipy = 2,2′-bipyridine), has been synthesized by a hydrothermal reaction and characterized by single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group C2/c with a = 19.967(4), b = 17.158(3), c = 14.276(3) ’, β = 129.623(5)°, V = 3767.4(12) ’3, Z = 8, C22H14N2O4Zn, Mr = 435.72, Dc = 1.536 g/cm3, F(000) = 1776, μ(MoKa) = 1.336 mm-1, the final R = 0.0777 and wR = 0.2447 for 2032 observed reflections (I > 2σ(I)). The Zn(II) ion is six-coordinated by two nitrogen and four oxygen atoms in a distorted octahedral environment. NDC ligand has a bis(bridging bidentate) coordination mode in the compound. The zinc atoms are linked by carboxylate groups of NDC ligand in bridging mode into a one-dimensional zigzag chain. The title compound, [Zn (NDC) (2,2’-bipy)] n (NDC = 1,5-naphthalenedicarboxylate, 2,2’- bipy = 2,2’-bipyridine), has been synthesized by a hydrothermal reaction and crystallized in monoclinic space group C2 / c with a = 19.967 (4), b = 17.158 (3), c = 14.276 (3) ’, β = 129.623 ), V = 3767.4 (12) ’3, Z = 8, C22H14N2O4Zn, Mr = 435.72, Dc = 1.536 g / cm3, F (000) = 1776, MoKa = 1.336 mm-1, 0.0777 and wR = 0.2447 for 2032 observed reflections (I> 2σ (I)). The Zn (II) ion is six- coordinated by two nitrogen and four oxygen atoms in a distorted octahedral environment. NDC ligand has a bis (bridging bidentate) coordination mode in the compound.
